File:Amon mugs battle raiden.png

This is Amon's facial expression from the SNES game Kishin Douji Zenki - Battle Raiden. Unlike the other bosses, he only has one mugshot.

Recently I found out that while Amon has two mugshots in the Japanese version of the game, the English version shows only one of them!

Chiaki, Zenki in his Chibi and Demon God forms and the other bosses also have such images ingame.
